【摘要】：目的依據(jù)肌力數(shù)據(jù)對沒有標(biāo)準(zhǔn)肌力流失模型時的老年人肌力進行量化評估。方法將加權(quán)灰靶理論運用到老年人肌力評估中,結(jié)合臨床經(jīng)驗,對老年人六個關(guān)節(jié)肌力流失程度劃分等級。運用灰度貢獻(xiàn)解決了各關(guān)節(jié)對人體肌力影響的權(quán)重問題。結(jié)果以一個70歲男性老人的慣用關(guān)節(jié)肌力數(shù)據(jù)為待識別序列為例得到其肌力加權(quán)靶心度為0.680 3,對應(yīng)到等級劃分的五個級別中為第二級,即輕微性流失。以一個老人在60歲、65歲、70歲、75歲、80歲時的關(guān)節(jié)肌力數(shù)據(jù)為待識別序列為例,其對應(yīng)的加權(quán)靶心度分別為0.577,0.612,0.689,0.831,0.729。對照評估等級,五次分別處在一級,二級,二級,四級,三級,即肌力能力在前四次都明顯衰退,第五次有所好轉(zhuǎn)。結(jié)論利用加權(quán)灰靶法可以科學(xué)合理的對老年人肌力進行量化評估。
[Abstract]:Objective to evaluate the muscle strength of the elderly without a standard muscle loss model based on muscle strength data. Methods the weighted grey target theory was applied to the evaluation of the muscle strength of the elderly, and combined with the clinical experience, the degree of the loss of the muscle strength of the six joints of the elderly was classified. Grey contribution is used to solve the weight problem of the influence of joints on human muscle force. Results taking a 70-year-old male as an example, the weighted target center of muscle strength was 0.680 3, corresponding to the second stage of the five grades, that is, slight loss. Taking the joint muscle strength data of an old man aged 60, 65, 70, 75 and 80 as an example, the weighted target centroid was 0.5770.6120.6890.6831and 0.729, respectively. Compared with the evaluation grade, five times were in grade one, two, four, three, that is, muscle strength declined obviously in the first four times, and improved in the fifth. Conclusion the weighted grey target method can be used to evaluate the muscle strength of the elderly scientifically and reasonably.
